Answer 1

Complete Question:

Adam calculates his annual commission, y, using the model y = 0.28 x, where x represents his total sales for the year. What is the meaning of the x-intercept in the model?

A) the x-intercept represents Adam's base pay

B) the x-intercept represents the highest salary Adam can earn

C) the x-intercept represents Adam's total sales when he earned no commission

D) the x-intercept represents Adam's commission pay when he had zero total sales

Correct Answer:

"the x-intercept represents Adam's total sales when he earned no commission" is the meaning of the x-intercept in the model

option C

Step-by-step explanation:

Here ,basically equation of straight line is given as  y = 0.28 x . x-intercept is when y=0 i.e.

⇒ $y=0.28x$

⇒ $0=0.28x$

⇒ $x=0$

Therefore , x-intercept in the model means when annual is commission is zero , as he haven't worked till now . So, correct option C).
